INSPECTION
1. DRAIN ENGINE COOLANT
2. REMOVE ECT SENSOR
(a) Disconnect the ECT sensor connector.
(b) Using a 19 mm deep socket wrench, remove the ECT
sensor and gasket.
3. INSPECT ECT SENSOR
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance: Refer to the graph
If the resistance is not as specified, replace the ECT sensor.
4. REINSTALL ECT SENSOR
(a) Install a new gasket to the ECT sensor.
(b) Using a 19 mm deep socket, install the ECT sensor.
Torque: 20 N´m (200 kgf´cm, 14 ft´lbf)
(c) Connect the ECT sensor connector.

INSPECTION
1. REMOVE V-BANK COVER
(a) Using a 5 mm hexagon wrench, remove the 3 cap nuts.
(b) Loosen the V-bank cover fastener counterclockwise.
(c) Remove the V-bank cover.
2. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
3. CONNECT LEXUS HAND-HELD TESTER OR OBDII
SCAN TOOL
(a) Connect the TOYOTA hand-held tester or OBDII scan
tool to the DLC3.
(b) Please refer to the TOYOTA hand-held tester or OBDII
scan tool operator's manual for further details.
4. INSPECT FUEL CUT OFF PRM
(a) Increase the engine speed to at least 3,500 rpm.
(b) Use a sound scope to check for injector operating noise.
(c) Check that when the throttle lever is released, injector op-
eration noise stops momentarily and then resumes.
HINT:
Measure with the A/C OFF.
Fuel return rpm: 1,200 rpm
5. DISCONNECT LEXUS HAND-HELD TESTER OR
OBDII SCAN TOOL
6. REINSTALL V-BANK COVER

manual for further details.
(e) If you have no TOYOTA hand-held tester, connect the
positive (+) and negative (-) leads from the battery to the
fuel pump connector (See step 7).
(f) Check that there is pressure in the fuel inlet hose from the
fuel filter.
HINT:
If there is fuel pressure, you will hear the sound of fuel flowing.
If there is no pressure, check these parts:

Fusible link

Fuses

EFI main relay

Fuel pump

ECM

Wiring connections
(g) Turn the ignition switch to LOCK.
(h) Disconnect the TOYOTA hand- held tester from the
DLC3.
2. CHECK FUEL PRESSURE
(a) Check the battery positive voltage is above 12 V.
(b) Disconnect the negative (-) terminal cable from the bat-
tery.
(c) Purchase the new No.1 fuel pipe and take out the fuel
tube connector from its pipe.
